This phone was on Boost. After having the phone in repair for 6 weeks I moved on to Verizon and Samsung. But this HTC is brand new since old phone could could not be repaired. I'd like to use the Desire in my house with WiFi. But it seems to have a memory record of being a Boost phone. I removed the SIM card but it still wants me to update Boost updates etc. Can I get this phone back to being just a device that can use apps?
