How to use edit key and format the phone?

Tip 1 : Do u understand how to utilize the edit key (abc or pencil key)?
Here is how... in your inbox for instance; u wanna erase multiple sms, just push and hold the edit key, scroll down, then, push c to erase the checked sms. The edit key can also be employed to copy and past text in sms, just push and hold it and scroll across, select copy. pretty effective for putting song names in N Gages

Tip 2 : things happens, on a smartphone, its unavoidable you do something inappropriate, and its calls for a format of smartphone. to format the smartphone, type *#7370#, then insert your lock code, which is the second code of your smartphone. NOTE: battery must be full, else if format is interrupted by low battery, outcomes will be disastrous
I got wind the code *#7780# works too,.

for 6600 users, to format the smartphone, there is an alternate technique. Press and hold <3>, <*>, and the buttons, then power on smartphone, keep holding on the 3 button, till you come to a format screen. This method exclusively works on 6600, and need not put down the second code. BUT second code would be readjusted to default 12345.
