Does anyone have the same or it's problem with my phone?
I'm attempt to upload generated image to my Motorola KRZR K1, when transfer done, the phone freezed for about half minute (especially on my favorite Matrix wallpaper). Key are not work, screen image freezed , but after that wallpapers work fine!.
Is my phone OK? Any suggestion about it?

Don't worry - your phone is OK!
The phone needs not only to copy your picture, but to prepare its thumbnail for listing screen. And some phones perform data base rebuild on each upload.
These procedures may take some time.

Most important that animations work fine on your phone.
