What model is your ipod MC or MB

my iphone is dead at the moment, the storm made me god damn wet, and so my iphone drown in all the water..

3.1.2, 3.1.3 use Spirit...

Jailbreak iOS 4 iPod Touch 2G Redsn0w or Sn0wbreeze...

iOS 4 has "Multi-Tasking", Folders that capacity is 12, much more stuff...

4.0.1 fixes the issue of the Reception so no more reception errors.
