Title show say: why am i NOT eligible for N1 upgrade. My 24mo contract expired in Dec '09. So, I'm thinking if I could upgrade to N1. So, I went to the google site, - get my phone - select the T-Mobile radio button - select No, I want to modify my existing individual plan - continue - select No, I want to modify my existing individual plan, then enter in my current T-Mo number and last 4 soc #, then select I'd like to upgrade the phone on my existing T-Mobile individual plan., then check the Terms and Condition - Continue - the system then comes back giving me the only option to buy phone @ $529. Did I miss something during the upgrade steps? Thanks!
