i was using my captivate last night and the 3g and browser suddenly turned off. i restarted the phone several times and let is sit all last night and all of today. i recently tried again but its still not up i have no 3g or 2g (edge) i can still receive texts and call but nothing to do with the browser. ive tried flight mode and everything else i could think of but nothing is working. any ides would be greatly appreciated!
