I would call and talk to retentions at sprint. Tell them your cellphone reception in your house sucks, the sprint store says your phone works as advertised, but you need better reception in your house or you will have to change carriers.
The other poster is right, they should give you an airwave. Make sure they don't charge you for it and comp your acct 10.00 a month to cover it. Some phone antennas just are better than others (even the same model phone).

p.s. Make sure you are holding it properly as well!!!
