Got a great plan with great minutes, but my phone gear is over 3 years old and the battery doesn't keep a charge. Thanks!
I am not sure what you mean when you say unlocked. But, what you can do is buy another battery. Every phone starts to lose it charge, some faster then others. It really depends on how much you use it. But if you search on ebay I found another battery for my phone for 12 dollars.
