Don't update until an untethered jailbreak is released for 7.0.1. Do not go for 7.0. The beta was very unstable. Multitasking gestures killed the system, (fixed by holding home and power for about 1 minute, then wait for the next 5 while IOS tried to figure out what it did wrong), low battery life, auto-unlock resprings the device, and headphones with inline mic controls were not supported until beta 5 and 6. The new, final release of iOS 7.0: 11A465 is somewhat more stable with support of peripherals. Jailbreaks should be released soon for 6.1.3 and 6.1.4.
Note to Jailbreakers:
Whenever apple releases a new iOS, wait until an untethered jailbreak is released for the iOS unless you can live without the features from the jailbreak.
