any wifi connectivity problem & battery draining for ios 6 upgrade?

yeah my friend me too have wifi connectivity problem after ios 6 upgradation and also my text messages are getting erasing automatically and music files also erased completely.

Some people are having problems, MOST are not. People who are having no problems generally do not visit technical support forums.

In my family I have an iPhone 4S, an iPhone 4, 2 iPod Touches, an iPad 2 and a new iPad all running iOS 6 without any problem whatsoever.

There will not be any problem if theres no interuption while you download your iOS6. I mean dont use ur internet for other purposes while downloading iOS6 because its a huge file and there's a chance for the file to get corrupted. So, I would say its better to update at night.
