Hi,
UIDs can be obtained from Symbian Signed for free of charge.
www.symbiansigned.comSign in and fill UID request form, its quite straightforward.
If you don't want to get your application to symbiansigned process at once, like usually, request UIDs from unprotected range.
When testing in your phone remember to check "App. Mgr" application "Software installation" setting, that it is "All"
Cheers
