ios4

My calendar synched with my iphone happily for two years. A few days ago it stopped working. I didn't upgrade the operating system. In fact - I did nothing at all at my end. I can just no longer view my calendar. Looking online, I'm not the only one and it appears to be a Yahoo (not apple)...

I recently bought an unlocked iPhone 3 from ebay yet as I'm trying to download apps I need at least the ios 4. I would like to upgrade without locking itself again any guidance from experts? thanks in advance!

Anyone know any free games that don't need ios4 to download??.. Fun ones please!!!

I love stratergy games that also like war scenarios such as CNC (already got that) and Hunters : episode one .and also is there and stratergy/mmog games for the iphone that are good? Any suggestions? Please Please Help

Is the Itouch 4g with the iOS4 worth getting even though i have a 2g? I kinda want to get it cause of the camera and the better cpu. But is it really worth like $230? And should i get an 8g or the 16g or whatever the next one is.

My computer identifies the iPod but not vice versa. I don't know what's the problem. I would really appreciate all the help you could give. Thankssss! (:

I have read many forums and advise pages on how to downgrade my iphone 3g from software IOS4 to 3.1.3, the only problem is need to put the phone is DFU mode, now i cannot do this as the power button on my phone is broken. Is there any other way to do it without turning it off. Thanks

I wondered if you can dual boot iPhone os 3.1.3 and iOS4. If you can, please explain how to do it.

I was thinking about purchasing a Kenwood KDC-HD545U CD receiver for my car, and was wondering if anyone knew if it works with IOS4. I have an iPod touch 3rd gen running IOS 4.0.1
