I recently upgraded my cell to 2.3.4 after my girlfriend got a replacement phone which came loaded with 2.3.4. After the update my data connection seems to drop in and out at random. neither of us had this problem before (I had 2.1 and she was on 2.2) but now we both have the same issue. It also can be noticed when tethering, downloads will just stop, pages will not load or not load fully. I have seem similar threads about this issue and Gingerbread on other phones. Does anyone know of a fix and if not how can I go back to 2.1? Gingerbread is nice but Im not going to waste my time fighting it everytime I want to do something that requires data connection.
