With the MMS debacle ongoing, iPhone users are desperately looking for reasons to like AT&T. The company has started its 850MHz spectrum upgrade, which should improve signal strength in buildings and overall quality.

iPhone users in some urban areas are already reporting improved 3G reception and performance. AT&T has confirmed upgrades in Atlanta, Las Vegas, San Diego, Fresno and Stockton CA. Atlanta, for example, is in the process of getting 540 new 850 MHz cell sites next to the existing 1900 MHz towers.

Lithium-ion batteries are our friends. They have a great energy-to-weight ratio, no memory effect and they don't lose a charge quickly when not in use. About one percent of these batteries is recalled due to problems.

Unfortunately, these problems can include overheating, spontaneous combustion and explosions. A French teen has reported hearing a loud hissing noise before his iPhone screen shattered during a call. The photo above shows the screen, which he says launched a piece of glass into his eye.

Now you can receive iPhone push notifications instantly every time a new email comes to your Gmail inbox. The app, called Gpush, has been released by Tiverias Apps and approved by Apple.

Users can select between several options to determine how they are alerted of new mail. The iPhone will vibrate, ring, display the email message sender and subject on the lock screen (like incoming SMS), or just show a badge of how many new messages have come in on the GPush icon.

Apple has been prolific in the patent department lately, especially when it comes to patents that relate to the iPhone and iPod Touch. The latest filing shows a process that would allow someone on a phone call to send files to the other party without ending the call or leaving the phone app.

The iPhone would automatically determine where to send the files based on the contact information of the person connected. Even if multiple parties are in a conference call, the person sending documents, emails, contacts or text messages could send this data in one step while still connected to any of the participants.
