Many iPhone users who have upgraded to the latest iPhone firmware 1.1.4 are reporting numerous improvements in the cellphone signal strength, alongside a fix for out of order SMS texts and better Bluetooth compatability with other devices.

“I am getting 2-3 bars and solid edge in the Chicago Union Station north bound Tunnels. Normally would be no bars and EDGE would be sketchy. Leaving the tunnel I get instant signal. Before it would be 5-10 min before I got even bad connectivity. Loving it!”

“I used to have an intermittent weak signal in my condo. No more since 1.1.4.”

The issues with SMS and Bluetooth appear to stem from the 1.1.3 firmware where many users reported the bugs with the order of saved SMS messages along with quite serious issues with third-party Bluetooth devices - many rendered incompatible with the iPhone.

Although early indications suggest that these issues have now been resolved in the latest iPhone 1.1.4 firmware update.
