Apple released the latest version of iPhone firmware yesterday. 2.2.1 does not appear to contain major updates but seems to cause problems with previously jailbroken phones. ZDNet Blog has a nice entry describing the update, lamenting the lack of progress in key areas (i.e. cut and paste) and makes a good point that if the update is meant to thwart the unlocking community, it is energy wasted as Apple will likely never win that “cat and mouse” game. Updates noted thus far are:

• Modem Firmware 02.30.03
• iPhone SDK 2.2.1
• Reports that Safari is “faster”
• Reports that it fails, “went into recovery mode right after update” and “had to restore”
• Rumored that 2.2.1 was released to support photo syncing from iPhoto ‘09
• Safari Now caches the last page in memory

More info to come, I’m sure and I will update as needed.
