Are you using an iPhone 5 (http://www.engadget.com/tag/iPhone5/?utm_source=Feed_Classic&utm_medium=feed&utm_campaign=Engadget)on T-Mobile? Are you in an area with re-farmed 1900MHz HSPA+ (http://www.engadget.com/2012/02/23/t-mobile-lost-more-customers-in-q4-will-launch-lte-in-2013-with/?utm_source=Feed_Classic&utm_medium=feed&utm_campaign=Engadget) spectrum? Well rejoice! Some enterprising folks over at TmoNews have hacked Apple's carrier update (http://www.engadget.com/2013/04/05/t-mobile-carrier-update-for-iphone/?utm_source=Feed_Classic&utm_medium=feed&utm_campaign=Engadget) for T-Mobile to boost data speeds on the 1900MHz (PCS) HSPA+ band. Better yet, this tweak applies to both T-Mobile's iPhone 5 and the AT&T / unlocked versions -- no jailbreak (http://www.engadget.com/tag/jailbreak/?utm_source=Feed_Classic&utm_medium=feed&utm_campaign=Engadget) required. While the official carrier update enabled LTE for the iPhone 5 on T-Mobile, it also decreased data speeds on re-farmed PCS HSPA+ spectrum for many users. The hacked file makes a number of adjustments: it enables Release 9 for dual-carrier HSPA+ and sets the band preference to "auto" from AWS (http://www.engadget.com/tag/AWS/?utm_source=Feed_Classic&utm_medium=feed&utm_campaign=Engadget).
