Problems with used sprint cell phones?

both these problems are part and parcel of going in for a used sprint cell phone. since the phone has been used a little,it took a toll on its processor and made it bleak. the need for activation arises because since it was bought by someone earlier and he might have discontinued his plan with the sprint earlier, you need to get the connection activated and register with your own details on the same handset. so need not worry ,just get in touch with sprint customer care and get yourselves the plan and tariff that suits you the most. and well as the slow processor is concerned, you shall get your handset checked with the t-mobile staff and if no major wear and tear has taken place,then use the same phone. and if the speed is bugging you a lot,you could anytime go in for a new phone.
