Today's a big day as DFT have released their HSPL RSPL tool version 3 for Windows Phone. Previous versions allowed access to GSM editons of Generation 1 HTC devices which is why they're able to run those custom ROMs that we've reported on previously. This latest version of the HSPL RSPL tool released today now enables support for two CDMA phones: the Verizon Trophy and Sprint Arrive (7 Pro). From the changelog:

  • Added support for 'SCHU1000' and 'PD291200' MIDs
  • Removed OTA update inside RSPL and HSPL, this allows to keep HSPL after
  • HTC OTA Zune update.
  • Added warning screen about 4.XX and 5.XX
  • But still NO support for 4.XX and 5.XX
  • Support for CDMA devices: GoldC and SparkW (Edit: Gold_C is the codename for the Sprint Arrive and Spark_W for the Verizon Trophy)
  • Wizard UI: only WWE support remains

This tool is the first needed to unlock the bootloader allowing the loading of custom ROMs onto the device. That means "ROM chefs" can now begin the cooking and testing of custom builds, eventually getting to the point where a stable version can be released to the public.

That's good news for those who don't want to wait for the latest build of the OS to get "officially" released (assuming it will even happen). In short, whether Verizon or Sprint officially release 8107 to fix the keyboard, you should be able to load a custom ROM with it in the near future.

Stay tuned for those custom ROMs over the next few weeks as we'll report any that come forth.
