HELP! I rooted my phone and I deleted some system apps, which seemed to me not useful (such as yahoo finance etc.) but I think I deleted some important apps too. What should I do?? After a few days of rooting showed a board with "Unfortunately, touchwiz has stopped" No matter, how many times I click okay, it shows again later. And the other problem that I can't get messages, it says "<> proccess com.android.phone has stopped". So what should I do?? Please help. Sorry, if the similar problem was on there, but I couldn't find it. And please explain me step by step. (I am not into those technical things)
