Hello, my first post, please forgive any mistakes! This is such a great resource of info!!! Thanks to everyone involved!! I just purchased a blackberry 7520 from ebay with no sim card. I put my sim card from my nextel i60 into the bb and everthing     

 seems great, however I cant seem to get complete data from the internet. I just ordered a" Correct " sim card from ebay.Would any one have any tips for me, to help with complete internet access? I also just called nextel to add the 10$ web package to my account.Thank you very much for any ideas!!!I also tried the net alert offered, and it said not valid subID Im pretty sure i found the right sub id thanks to your site on my phone
