The CallerID Fix Collection by Frank8 (iSpazio Repo) has been released for the iPhone 2.2 firmware. This patch will enable Caller ID for those countries not supported by the iPhone.

Number match betwen received Calls or SMS and the Address book happens only

Those informations are extrapolated from a database using as access key the country code in the Sim-card, if you see the number and not the name may be those informations are wrong or missing.

2.2 Battery Issues Fix

Several users have reported diminished battery life under iPhone OS 2.2. A pair of Apple Discussion threads–one with 59 replies (“iPhone Update 2.2 Drastically Reduces Battery Life”), the other with 78 (“Battery drain since upgrading to 2.2″)–chronicle the issue. Sample reports include:

One fix that has proven successful for some users experiencing this problem: delete then re-establish any push-capable accounts (Exchange, MobileMe). Failing that, delete and re-establish all email accounts.

We’ve published a number of potential battery-life boosters, including:

Drain the battery completely Use your iPhone until the battery dies completely (indicated by a battery icon appearing on the screen when the sleep/wake button is pressed), then fully recharge the device. It appears that the full discharge may reset circuitry that prevents a full charge from occurring, despite iconic indication of a full charge.

Turn off location services It appears that the Maps application and some third-party applications that use GPS functionality fail to power down the necessary hardware components when they are no longer in use. Navigate to Settings > General > Location Services and turn these services off when you are not using Maps or another location-enabled app.

Turn off Push then restart The iPhone 3G’s Push functionality for Exchange and MobileMe accounts can destroy battery life. Turn this option off in “Settings” then restart your iPhone by powering it off then on.

Restore the iPhone with original settings Launch iTunes and select the second option in the “Version” section on the Summary page for your iPhone. This restore process will erase your iPhone software and data, including all settings, which can be restored later via iTunes.

2.2 Undocumented Features (Yes More)

“Update All” back The ability to update all applications with the press of one button–a feature that was disable in iPhone OS 2.1–is back in iPhone OS 2.2.

Locked screen screenshots iPhone OS 2.2 now offers the ability to snap images of the locked screen. To take a screenshot: while holding the home button, press and release the sleep/wake button. A screen flash indicates that that the image was captured.
