Flashing radio to European G1 via Amon_Ra process: which version of radio 2.22.19.26i is safe for DangerSPL?
Those are the same radio. the file name is just different. notice the version number in both is: 2.22.19.26i. The first update-script was modified a bit so it supports both the dream (adp1/g1), and the magic (adp2). The OTA radio looks like it was specifically for the dream. 

I, myself, would use the one that is for both the dream &amp; magic, but really, it shouldn't matter.
