T-Mobile's One plan rubbed a lot of people the wrong way: sure, you got unlimited on-device data, but anything better than 480p video or 2G hotspot tethering was going to cost you an arm and a leg. The (un) carrier isn't deaf to your complaints, though. It's modifying its strategy to not only tackle key gripes with the One plan, but add a second plan that covers what gaps are left. The base One plan (still $70 per month for the first line) now includes 512Kbps unlimited hotspot data instead of 128Kbps -- still pokey, but you can at least do more than check your email. Also, October will bring the option of daily HD passes that, at $3 per day, are decidedly more affordable when you only want high-quality video for a weekend trip.
