Sometimes the Photo app will suddenly pop up an error message stating "There is not enough disk space to continue taking photos." This Cannot Take Photo message is letting you know that the iPhone storage space is full, which must be corrected before you can take more photos or videos.
Twitter has taken off lately with native iOS integration in Apple's latest firmware. The Twitter app is also available for free on the App Store, providing an easy way to access the service on the go. Lately some users of the app have experienced an issue where the Connect tab does not show @mentions.
Mashable explains that the mystery bug is affecting Android users, too. Although Twitter has not released a fix yet, there is a simple workaround that should solve the problem on your iPhone. Reinstalling the app or rebooting your iPhone is not necessary.
The Corona 5.0.1 Untether package has received another update, this time to correct an iBooks problem where images failed to display or displayed incorrectly after installation. Chronic Dev Team released Corona 5.0.1 Untether to free tethered jailbroken devices including the iPhone 4 from the need to reboot with a computer.
After installing early releases of both Corona and the redsn0w jailbreak for iPhone 4 and 3GS devices, some users had problems with iBooks including a Configuration Error dialog. The latest version of Corona (1.0-7) should fix both iBooks errors and can be installed directly from Cydia on a jailbroken device.
Some users have experienced an issue when dialing out on the iPhone 4S. Outgoing calls sometimes will result in the caller not hearing any audio, including the other line ringing. Apple has not addressed the issue, however there are some temporary fixed that might work for your device.
If the problem persists, you may be able to ask for a hardware replacement at the Apple Store Genius Bar. Before this happens make sure you have tried to completely restore your iPhone 4S. Here are some temporary fixes to try:
Some iPhone 4S users are experiencing a strange, involuntary mute when dialing out using their mobile devices. The problem is that the person dialing out can't hear anything on the other end of the line, not even a ringing phone. People receiving the calls can hear the iPhone 4S owner just fine. An Apple discussion page titled Outgoing call no audio started almost immediately after the iPhone 4S was released and has leap over to additional discussions.
Although Apple was quick to respond to complaints about iPhone 4S battery life being shorter than expected, there's no official word on whether or not a fix is in the works for the audio issue. Some iPhone owners who experienced the problem were able to correct the issue with a full restore. Others who have not had luck fixing the problem have begun to call the issue Audiogate.
