After years of customers waiting, T-Mobile and Apple are finally kicking off pre-orders for the iPhone 5 ahead of its 12 April availability.

The iPhone 5 will be available on the UnCarrier for $99.99 (£65) down and 24 payments of $20 a month. Customers can also pay the full price of $579.99 for the handset to get it unlocked, which is $70 less than how much Apple offers. 

T-Mobile will also offer the iPhone 4S for $69.99 down with payments of $20 a month and iPhone 4 for $14.99 down and monthly payments of  $15. The iPhone 4S and iPhone 4 will be available in "select markets", according to T-Mobile.

The UnCarrier pricing is radically different from what other carriers offer in the US. But T-Mobile's pricing has been heard of in Europe, where Three offers similar. Still, T-Mobile is moving in the right direction for the folks stateside.

"Customers start with a base rate of $50 per month for unlimited talk, text and Web plus 500MB of high-speed data. They can add a second phone line for $30 per month, and each additional line is just $10 per month," T-Mobile explained to Pocket-lint. "Customers can add 2GB of high-speed data for $10 per month more per line or get unlimited 4G data for an additional $20 per month per line. No caps. No overages. Just simple value."

T-Mobile is the last of the big four carrier in the US to offer the iPhone. 

"T-Mobile is taking a different approach because Americans have had enough of our competitors’ restrictive wireless contracts that lock them on to slow, congested networks," the carrier told Pocket-lint. "T-Mobile customers will never have to be shackled by a two-year service contract."
