I have just used greenposi0n to JB my iPhone4 yesterday. Everything works pretty well. However, I just noticed that every so often, my 3G connection simply dies. I have 3-5 bars of signal and the 3G word is on the status bar. But every app that tries to access the internet times out (this is especially noticable on Cydia. It fails to get an updated app list from the repos) If I turn off the 3G and then turn it on again, the issue is resolved. But this soon happens again. Reboot of course works as well. The following is the list of JB apps I've installed: biteSMS five icon dock lockscreen clock hide SBSettings Slanted Lock Typophone 4 Winterboard Does anyone else have similar issues after JB'ing?
