Today i took the plunge and decided to download a few apps. I downloaded 4 Apps from the Android Marketplace. The 4 i downloaded were: Advanced Task Killer 3G Watchdog Real BlackJack Talking Tom Cat No problems downloading, installing or using the apps. Everything seemed perfect until an hour or two after my i was texting someone and suddenly i couldn't send texts to anyone. I can still recieve them and make/recieve calls. I was actually texting no problem after the apps were downloaded and installed but then it suddenly changed. I deleted and uninstalled all the apps but the problem persists. I even tried restoring the message settings to factory settings but im still having no luck. Any help would be greatly appreciated.
