With Apple releasing iPhone v2.0 firmware betas left and right, the iPhone is shaping up with support for more and more features. The latest iPhone firmware beta has revealed that the next firmware revision will enable FM radio and 
FOTA (firmware over the air) support on the iPhone.
FM radio support could point toward the iPhone working with FM radio-products like Apple’s “iPod Radio Remote” that essentially allows iPod users to listen to broadcast radio. FOTA support indicates that future firmware updates could be rolled out over the air, with no need to synchronize the iPhone with iTunes in order to update the device’s firmware. With the iPhone 3G’s faster data connection allowing for software and firmware updates through the cellular network, firmware updates could become even more streamlined and hassle-free than its current form.
Unfortunately, OTA firmware updates could mean that Apple could possibly send software updates that will re-lock previously unlocked handsets wirelessly.
You gotta take the good with the bad – OTA firmware updates may prove to be more good than bad.
