Since I bought my 8310 from an authorized agent instead of a corporate store...my local corp store said they couldn't give me the credit today. And, since the deal was only good online or at a corporate store...my agent store couldn't help me either.
No big deal, since I am very happy with my current phone. And...I guess not having to reload apps, wallpapers, ringtones...or mess with personal setup again is worth $99. At least, that's what I keep telling myself anyway...
