T-Mobile USA will reportedly launch the HTC One nationwide next Wednesday, June 5. The carrier has already made the device available at 300 stores across the United States, but now that HTC has increased production and ironed out those initial supply constraints, T-Mobile customers will be able to get it pretty much anywhere.

That’s according to a source for TmoNews. It hasn’t yet been confirmed by T-Mobile — so please bear that in mind — but TmoNews has a very good track record when it comes to T-Mobile rumors.

T-Mobile charges $99.99 upfront for the HTC One, then $20 per month for 24 months after that on a T-Mobile Simple Choice plan. Alternatively, customers can buy the device outright for $579.99, eliminating that additional $20 fee for the handset each month.

For BlackBerry fans out there, the site also reports that the new BlackBerry Q10 will also be available on the same date. Like the One, it’s expected to be priced at $99.99 down with 24 monthly payments of $20 after that on one of T-Mobile’s Simple Choice plans.
