The iCup is a SmartPhone peripheral, and later smartphone proper, created by Fig Corp. that serves as a liquid container and bioinformatics extension. It was initially an optional peripheral, but became so successful it would soon become a central component of the smartphone. Later versions would be sold with the phone built-in, so that it might even be difficult to find a phone without a container attached.

Origin

The iCell was 2007's revolutionary development for mass surveillance, but it had a few drawbacks. During about 5% of waking hours, users would have it in their pockets. This muffled the microphone and blocked the camera, making it a lot harder to know all the piddling shit people get up to. This was an annoying blind spot for data-collectors public and private, who made their discontent known to Fig Corp.

Fig Corp. never lacked for new market innovations, so they went to work. Their market research found that one of the most commonly carried items for people of all demographics was some form of liquid container: a cup, water bottle, thermos, etc. 

Based on this information, the iCup was born in 2028: various types of liquid container with built-in docks for smartphones. Crucially, it was too large to store in a pocket. 

Impact

Culture conveniently followed suit, and it became the consensus that it was stupid or creepy to keep your phone in your pocket rather than attaching it to a Cup peripheral. Soon, Cup phones were the new norm, and many manufacturers stopped making smartphones that weren't built into a liquid container of some sort.

Backlash

The inability to lay the phone in such a way that the camera or microphone were covered brought a predictable backlash from Anti-Surveillance voices, but this product was not revolutionary in that regard. It simply increased the encroachment of surveillance, but not in new ways - at least in ways that people understood yet.

A Viral Meme circulated, I See You Pee, first as an objection to the increased surveillance opportunities. Then, a Countermeme by the same name arose as a defiant acceptance by Tech Lovers - people uploaded videos of themselves pissing for a good three months apparently to try to show that surveillance didn't matter^†. 

Features & Peripherals

iCup

• Heating & cooling modes for contents, including Slush & Boil modes
• Waterproof, soundproof, smellproof liquid container eliminates spills, sloshing noises, and can even store your weed safely
• Pressure release valve from hot liquids slightly extends phone battery life
• Sense and display various information on contained liquids: temperature, composition, common toxins, etc.

iSuck

• A Revolutionary BUTTON - That's right, it's a button, too! Bite the end of the straw to do things! This functionality was critical for many apps, which encouraged most users to keep the straw in their mouths the entire time they use the phone - keep this in mind.
• Built-in bioinformatic sensor - Drink something from the straw and it will sense various things about your body's current state: pulse, blood pressure, hormonal secretions in saliva, blood oxygen & electrolytes, blood sugar, bioelectric shifts, etc.* 
• Temperature modulator - Drink boiling or freezing liquids safely, as the straw will heat or cool them as needed before they reach your mouth
• Blow me - Blow really hard into the straw and the pressure release valve will kind of sort of charge your battery, kind of.
• Extendable - Telescoping and flexible structure allows you to suck while you use your phone, even more than you already do.
• Program me to program you - Surreptitiously, the iSuck could send subliminal audio or data signals to the user's brain. This was built into the design at the behest of the Central Intelligence Agency (CIA).

Additional peripherals

• CondenCity - Draws moisture from the air, filling the liquid compartment with particularly pure water
• Steeple - Store a whole pot's worth of tea leaves and steep as needed, enjoying fresh tea whenever you want
• Electro-Lyfe - Store electrolyte crystals, and automatically release them into your water depending on your own levels (requires iSuck)
• "Yep, there's a DongLe for that!" - The iCup and iSuck naturally require dozens of expensive DongLes, which Brand Loyalists are happy to pay for.
• The Vapist StrawMan - iSuck competitor. The liquid compartment is filled with Vape Juice, and the StrawMan is a vaporizer used like a straw. Nowhere near as popular as the iSuck, though. Vapist went bankrupt in 2037.
• Breazy - "Breathe eazy!" The iCup condenses a small supply of pure oxygen if you're otherwise too broke to survive EarthsDeterioratingAtmosphere.
• Pump it Up! - Pump your stomach with our new wide-mouth straw. Not for bulimics**.

Popular Apps

• Bubble Bunny - Bubble Bunny has to get to the other side of the ocean inside a bubble, where his MerBunny love has been kidnapped! Blow into the iSuck to make his bubble bigger, or suck to make it smaller. Can you dodge the nefarious Poppers and their minions?
• DriveSafe - Breathalyzer. Not recommended if you store alcoholic drinks in the iCup, but we're not your mommy.
• Piranha-yama - Too busy to do three-part breath? The iSuck cycles your breath automatically so your employer can technically claim you don't need breaks for personal well-being!
• AnaLock*** - Mix water with an AnaPack food supplement powder in the liquid compartment, and AnaLock will mete it out according to your blood sugar levels and caloric needs for an ideal rate of consumption to promote weight loss. Caloric needs are user-configurable, and the iStraw has a lock setting to ensure you don't exceed them.

Bioinformatic Data Collection

By Advertisers

The iSuck, by virtue of the conductivity of a water connection near-adjacent to the human brain, was a massively effective medium for covertly interfacing almost directly with the user's mind. Advertisers could now know almost precisely which junk food, porn, games, etc. would be irresistible to you.

By the CIA (Project Moonstruck)

This development largely supplanted Radiopsychic Broadcasting (RPB) as a method for reading and influencing the public's thoughts.

The iSuck could send bursts of data or audio directed at the user's brain or ossicles, subtly influencing them to the whims of whoever had the means to control it.
