A guy named shadowmite released a
2-byte patch for those frustrated Sprint users who weren't able to use the Bluetooth Dial Up Networking (DUN) profile on their Treo 650.
As a reminder: Sprint decided for unknown reasons to cripple the use of Bluetooth on the new Treo 650 for laptop Internet access. Now it is quite obvious that the reason was not of technical nature, otherwise how could it have been "fixed" by merely changing two bytes?
Here is how to install the patched file (as explained by a Treocentral user):
1. Turn off Bluetooth on the Treo
2. Soft reset (a precaution).
3. Use the install tool on your computer to install the patched file. Hotsync.
4. Soft reset your Treo (just in case).
5. Start Bluetooth and turn Dial-up Networking on.
