"Unlimited Cell Minutes

Never use your N900 cell minutes ever again. T-Mobile has MyFav5, simply make one of these your GV number. When you call your GV number, it'll ask you for your pin, after you've entered it, you'll be told if you wish to make a call press 2. After you've pressed 2, enter the number you wish to call, area code first and BAM you've saved your minutes. Give out your GV number, so when someone calls, it goes to your cell and you're covered under the MyFav5 so again...minutes not used!"
