does sprint sell replacement samsung rant batteries?
well, if the whole phone dropped in the soup.. then perhaps its not the battery at all instead its the whole phone. This is where the insurance for 7.00 is good to have, but
If you need a battery for it, if you walk in to a best buy, radio shack in sure they have them for 50.00. , I know definitely at a sprint corp store the do either in inventory or via their warehouse, and they go about the same 50.00. Plus they come with a 1yr warranty with the store, so if they battery is acting up ( doesn't cover physical damage though) like holding a charge.. and etc. They'll exchange it at no charge within 1 year and its the original product, not the bootleg ones.
The difference are that the bootlegs can damage your phone, and they usually don't work as well.. so go for the manufactures batteries like samsung or a sprint store.
good luck.
