Okay, so I updated to iOS 4 today, (jailed, because 3.1.3 was done with Spirit... =/) and i am having A LOT of problems with EVERYTHING. Ive got an 8GB late 2009 MC-model iPod touch, and heres a list of some of the problems: 1) WiFi When I hold the device with one hand, and have 4 fingers on left, and thumb on right, with palm resting on the steel on the back, It goes from 3 bars to one, and 54 Mbit/s to 1-4 Mbit/s. holding it ANY OTHER WAY is fine. Didn't have this problem at all before.... 2) Locking When I LOCK the device, it seems to disable ALL the external controls for about about 5 seconds, then registers EVERY button pressed during the time-frame. If I'm listening to music, I will press the Vol + button a few times... then a few more.... then a lot more, because it doesn't register. THEN it will register them ALL and blast the volume to a point unbearable to even have headphones in. 3) Unlocking When I press the unlock button, it will sit for a few seconds, blank screen, then it will power up the screen. Will sometimes take 10 seconds+ if I'm listening to music. Then I slide the slider, to have it lag for a few MORE seconds, then finally display the passcode entry, which itself lags, then after complete, will continue to idle for about a second, then unlock. 4) Compatibility/USB Not sure if it's hardware or software, but when i plug it into either my dock, or USB, it wont register its been plugged into anything for a good 5 minutes. It NEVER did this at 3.1.3.... So far thats a few of the major things. Anybody else with these problems though? It's really starting to get annoying, and making me consider selling the thing. Anybody?
