For those who are unfamiliar with AGPS Patch, XDA Senior Member crypted gives a brief explanation:
This patch was created to provide quick GPS locking across North America. But, it has been ported into a worldwide solution for multiple devices. Using a general ROM without this has resulted in 10+ minutes of GPS delay. Also, GPS lock kept being lost. By using this patch, most people experience a GPS lock within 10 seconds (2 – 20 seconds range can be expected). Typically, a device using this patch will lock onto 7 – 9 satellites. Users have reported up to 11 satellites being locked at once. Without this patch, the average satellite count is 4.
Well, now users who own a HTC Desire S join the already impressive list of supported devices who can utilize this patch. With three ways to install the device, including ClockworkMod, ADB Push and just copy/paste the files into the correct directories, users of all knowledge bases will be able to find the way that suits them best.
Additionally, scripted’s original thread contains pro tips for getting your GPS to work better and an FAQ that has virtually every possible reason why your GPS isn’t functioning from the case getting in the way of signal to a rare bug that prevents usage entirely.
While there’s a list of supported devices, scripted says:
you can use any build with any phone. You may have good luck with specific builds that do not fit your phone or carrier criteria. If you’re curious, test it and see.
So for anyone who’s interested, check out the thread linked above.___________________
