    Over the past week or so my iPhone 4S signal has started to "jam" occasionally. It will show that I still have signal, but the bars won't fluctuate and I can't use any data. Usually switching airplane mode off and back on doesn't help either. I have to completely power the device off and back on. Sometimes if I wait 5 minutes or so, it'll come back to life.

    Has anyone else had a similar issue?

    I have had this happen also. Only on 3G, never on WIFI. Only fix is usually restarting my 4s. Frustrating.

    This seems to be a widespread issue. It's a big discussion on Apple Discussions

    Users from around the globe are reporting this. I'm on the Meteor network in Ireland and it's the same thing. Phone shows 4- 5 bars at times but on occasion, if I try to SMS or make a call, nothing. Phone will then drop off the coverage saying no service and will then start searching and will hook back up to the network then.

    Some users speculating this is a baseband issue, he showed the diagnostics report showing this.

    The question is, is this a widespread issue or is it a particular batch of phones that have a fault? There are clearly phones that don't have this issue, or maybe users haven't found this issue out yet

    what network are you guys on?

    it might be helpful to see if its GSM or CDMA

    also it could be the 2 antenna's switching back and forth. maybe its getting stuck on one of them or something

    Skynet is merely testing its control systems.

    No need to worry.

    I would think the upcoming 5.0.1 has quite a few issues to fix. This is just yet another one. I haven't experienced it on my vzw iPhone but my fam has AT&T and they have had this. Maybe just a small difference in there firmwares. Hell, I may see this any minute now.

    I had this problem with my 4s on ios5. I installed 5.0.1 beta 2 and can confirm this issue is fixed.

    This happened once for me, showed 4 bars 3G but couldn't pull any data. After I restarted it was working again.

    And apparently it was in that state for a while as when I restarted I had a bunch of email that it had missed.

    Hasn't happened since then, at least that I know of.

    I'm also experiencing this problem 3 or 4 times a day; it's very annoying.

    Same problem daily on my 4S.

    Extremely annoying. I've had nothing but problems with this phone (yellow screen, **** battery, and this problem). Should've just kept my 4.

    Anyone resolve this? It still happens to me in 5.0.1 and after talking and trying everything with AT&T and Apple. I just can't figure it out. I love in Boston and work in Providence and it does seem to happen more often during the day in Providence.

    Had a friend with a similar problem. If I remember right, he said the genius bar just did a "reset all settings" and that worked for him.

    Yes I had this similar issue few days back but for me turning on/off airplane mode fixes my issue. I even popped the same sim to my iphone 4 to see if it was the network issue or the phones, and clearly it was the network issue as my iphone 4 did the same.
