Hello, This is my first post and I need help. I have a Samsung i7500 with android 1.5 and I installed a program - Kaloer Clock, then when I played with the clock, it suddenly went to the phone operator splash screen and stop responded. I cannot power down and I removed the battery and power up again and it stops at the same screen. Is there anything I can do to revive my phone? Please help. Thank you very much.
