i have prom, and i was checking to see if i can put my sim card into a smaller, older phone because i font have a skin or anything, and i dont want to take any chances with my new phone. it fits, but i took it out 3 times 1 to see if it fit in the phone, 2. to see if it actually works and 3. to try and load numbers. i was watching tv, and i go to text my friend, and my phone wont turn on. i hold down the power and the circle button for 10 sec. and finally it worked. is there a hardware problem? ive had no problems with it other than this..
