Also, phones can be direct-purchased from some manufacturer's, most notably Motorola. They will ask you who you're carrier is, and ship the phone US Cellular-branded. These phones can be activated.

No...US Cellular is a CDMA and T Mobile is GSM. Incompatible.
Any time you restore an iPhone you will lose your jailbreak and your unlock and you will have to start from scratch and do it all over again. You also cannot use a Boost SIM card in an iPhone as Boost is owned by Sprint/Nextel and their SIM cards use iDEN technology, not GSM. The Boost SIM cards can be used for International Roaming only and will not work on GSM networks in the US.
The short answer is no. Boost's newer iDEN phones do use a SIM card that can be used in GSM devices for international roaming but they will not work in GSM devices in the US. Most iDEN phones are not compatible with GSM networks, and GSM phones are not compatible with iDEN networks.
