You may loose data connection. I see sign 3G, see "hourglass" trying to connect.
But no more. Needless to say Fido representative has no idea how to solve this.
Sent me to Apple paid support.

I'm still rolling with a 3GS. iOS 5 almost bricked my phone, ran like absolute junk after the update. Naturally, i was pretty hesitant about updating again to iOS 6 but im glad i did. Phone runs waaaaay better now than it ever did on iOS5.
cant say if it is from the upgrade I did Saturday afternoon the 29th, yesterday, but all was good till this afternoon, iPhone 4 touch screen jumpy, I guess I would say, texting: touch the letter 0 once and I get 4 of them and another letter, singing in with 4 numbers, says to me wrong password 4 times, then on the 5th it recgonizes it, screen goes in and out when touched. know idea what is going on, never had this problem in the year I have had Iphone 4, so curious if it is from the upgrade? that was almost a gig of info it put through..I did take out the sim card wait 30 seconds and replace twice but to no effect.
Just an update don't want to give out wrong information, my iPhone 4 problem was solved with powering off, wait then power on again, no more touchy screen and no more filling past the screen and coming in again, thought it might have been iOS 6 upgrade as in the timing of it and never experiencing this anomaly before, but no just fixed with a simple power off and on again. So in retrospect my iOS 6 upgrade is great, other than the music dose not show album covers when in albums like it did before and smaller icons, when you choose a album it shows the cover but not in the initial page.
