after ios5 update My Ipod keeps crashing, and the internet stops but shows wifi sign
Well, this all happened after the Ios5 update to my ipod touch 4th gen. The problems are that when im using my wifi, it just stops as if im not getting any reception, but it still shows the wifi sign on the top left corner. A temporary fix for this is to go to settings and put my ipod on airplane mode off and on to get it to work for like 5 minutes. Its really annoying when watching videos or on facebook, etc. The second problem that I've been having is that certain apps keep crashing on me, one that does it the most is safari, it seems to crash all the time for me and now my facebook, news apps, among others all seem to crash. I dont know if this is a problem with the update, but it sure seems like it. Is there any way to fix this?
