IPhone 5 with iOS 6.01 WIFI to 3G/LTE problems

I'm using an iPhone 5 with iOS 6.01...Whenever I leave my wi-fi range and it connects to 3G or LTE, I cannot use the network, safari requests stand still, texting doesn't work, basically all network connectivity is gone. I have to reset the connection by turning airplane mode on then off. I've only noticed this after the 6.01 update. I tried doing a hard reset but it didn't solve the problem. Anyone else in the same boat?

I have the same issue.  Had it with 6.0 and now the same with 6.0.1.  It also happens for me after I've been on a call for a period of time.  You can also turn off and then turn on the data connection in the Cellular options as an alternative to the airplane mode.  I have not seen any clear answer to fix this issue in the discussions.
Apple Support today had be restore my setup on the iPhone again.  I'm waiting to see if anything from the restore has resolved this.  I also pulled the sim card and let that reset as well.
