So over the past few days, anything data related on my iPhone 3GS has just stopped working and will not start working again until I completely power the device off and turn it back on. For starters, my email seems to not be pushing and will only grab the mail when I open the mail application. Trying to load apps that require a data connection the app will time out and say server error. It's been doing this the past few days constantly. This is my first iPhone and I'm within my 30 days and if these are the types of issues that I've been hearing people talk about I can see why people are returning the device and I'm about to return it and get my BlackBerry back.
