iphone 3G voicemail notification

[z3r01]

so i bought a 3G on craigslist brand new unopened sealed box, then i used winpwn to jailbreak and activate it , popped in a new tmobile sim card juss for the hell of it(since i kno it cant be unlocked yet unless yessim/turbo sim etc)...today, i popped in my old tmobile sim juss to import the contacts and when i did, i have a new voicemail! but it still no reception/no service....dunno if its important to post, but i thought i'd share it with you...heres a video

Not sure what it means, but it use to happen on my old previous generation iphone that wasn't unlocked. Does it on the 3G one too.
