    Ever since I've upgraded to latest os, whenever I sleep my phone it switches to 3G in a few minutes. However when I connect to my librarys it stays. Anyone else experiencing something like this?

    not that, but mine doesnt vibrate sometimes from texts and once just randomly turned off during a call

    are these known bugs or what?

    I have an iPhone 3G, and have had the persistent wifi problem once before.

    I've also had an issue where, after a call, the speakers were completely muted even though the volume was set to maximum and the silent-ringer switch was off. I tried switching the ringer switch on and off, turning the volume down and up, no fix. Until I restarted, I had no volume whatsoever. :/

    hey forcetactic, I'm actually experiencing the very same thing.

    When I press the sleep button on my phone to 'wake it up', it sometimes shows 3G for a split second and then wifi, hope it's fixed by 4.1

    yes, this is a bit annoying because it worked perfectly fine in 4.0.1

    No problems at all on my iP4, using OS 4.0.2.
