Hi, I downloaded and installed this ROM, but I'm experiencing a fairly important bug: if I connect the USB cable to the computer everything works, but if I connect it to a generic 5V USB power supply the interface slows down to a crawl. Seconds and seconds pass between touchscreen input and the phone registering it, and sometimes it doesn't register it at all. Unplug, and suddenly everything goes back to normal again.
Can I fix this? I intend to charge the phone from a generic charger often, and this is a serious problem.
Edit: also I'm trying to download version 2.2.1 from
here, but the dropbox link provided is constantly down. Is an alternate link available anywhere?
