Last night T-Mobile released OS 4.6.1.231 for the BlackBerry Curve 8900. OS 4.6.1.250 is actually the latest official OS for the 8900, but I figured I’d post this for those that only like using their own carrier’s OS.

• Device Fixes
  • Improved battery life
  • Improved software performance and stability
  • Improved UMA and data performance
  • Enhancements to audio and speakerphone
• Resolved Known Issues
  • Message icon and myFaves interface disappear after Enterprise Activation
  • myFaves contacts display an hourglass after a software upgrade
  • Missing myFaves user interface missing after a SIM swap
  • myFaves user interface missing after a SIM swap
  • Error: ‘Uncaught Exception’
