Last I looked at my phone and there was a number "1" in the red bubble on the cydia icon. I clicked and it told me I had 6 update changes in my apps or files. I went ahead and did the updated changes. Shortly after the updating was done, wifi was picking up the connection, but no wifi speeds nor the symbol on the top. I restarted the phone and that didn't help. The icon symbol appeared briefly for a few seconds, then turned off. I have the iPhone 3g for tmobile. I jb with quickpwn 2.2. Could the update changes cause my wifi to not work anymore? In this case, what can I do? Thanks
