T-Mobile today announced a handful of device and service promotions that will become available over the holiday weekend. To start, T-Mobile is offering a free memory upgrade to buyers of the Samsung Galaxy S6 and S6 Edge. From May 23 through May 25, the 64 GB model will cost the same as the 32 GB model. Customers who buy the 32 GB will receive a $50 Visa gift card. Following their appearance on T-Mobile's web site earlier this month, the company shared pricing details for the LG Stylo and Leon. The Stylo will cost $289.92 at full retail or $12.08 per month and the Leon will cost $149.76 at full retail or $6.24 per month. T-Mobile Prepaid customers can score the Leon for free with an online rebate. T-Mobile-owned MetroPCS will also sell the Stylo and Leon for $199 and $49, respectively, after online rebates. Customers who switch to MetroPCS from a competing carrier will receive a free LG Leon or $50 toward the phone of their choice. Last, MetroPCS is recirculating the 4x100 promotion. Customers can get four lines with unlimited talk, text, and 2 GB of data per line for a total of $100.
