They might, but I think they need to plan way a head of time because they know that once untethered jailbreak coming out. Lot of people will be updating to 5.0.1 so they can take an advantage of this untethered jailbreak. If Apple update their 5.0.1 firmware in their server within the next few days (assume they can plug the hole that fast)without telling us, they will screw us big time.
Also, if you look at 3GS phone, we all assume that 3GS can install Ipad baseband. With the recent 3GS, they change something inside, 3GS manufacturer in 2011, week 35 or above, there is reported that we can install Ipad baseband onto it.
