As expected, Rovio has released 15 new levels for Angry Birds Seasons to commemorate the arrival of spring and the Easter holiday. Version 1.4.0 for iPhone features pigs with bunny ears and plenty of Easter eggs. There are also bonus levels that can be unlocked by liking the game on Facebook from directly within the app.

The update is free for those who already own Angry Birds Seasons, but if you haven't joined the fun yet it's only $0.99 for all of the holiday levels ($1.99 on the iPad). Previous releases include Halloween, Christmas, Valentine's Day and St. Patrick's themed levels with the same basic game that Angry Birds fans have become accustomed to playing. Rovio continues to expand the Angry Birds franchise with new software on the horizon.

T-Mobile fans rejoice. New evidence points to Apple actively testing a variant of the iPhone 4 on the carrier's network. This story seems to contradict previous reports that the iPhone would not come to T-Mobile anytime soon, despite a merger deal with AT&T. Should the next iPhone be launched in September, the device very well could make its way to T-Mobile customers. The photo below from BGR shows a test unit in white with the carrier name listed as T-Mobile.

Engadget reports that Vodafone UK already has the white iPhone 4 in stock. The device has made it into inventory computers and one source even sent photos of the packaging seen below. Apparently some lucky customers were sold the white iPhone 4 ahead of schedule, with the store employees noting the sale as a common black iPhone 4 to fly under the radar.

Vodafone told their crew to hold off on selling the highly-anticipated handsets "until next week" according to the report. Is it possible Apple would launch these white models in the UK without giving the US some white iPhone love? After all, retailers stateside have been spotted preparing for the white iPhone for months, and promotional materials have clearly stated the device would launch in spring of this year.

Questions surrounding iPhone tracking have exploded recently thanks to the revelation that cellular-capable iOS 4 devices have been recording their location accurately and consistently since the firmware installation date. All of this location information is logged in a single file that can be parsed and mapped by the new iPhone Tracker application. Although some users don't care about this kind of thing, others are concerned and will want to stop their mobile device from logging location data.

As it turns out, turning off Location Services under Settings will not help, as this only controls the GPS chip inside the iPhone. Security researchers Pete Warden and Alasdair Allan have discovered the location data comes from cellular network tower triangulation, which doesn't require communication with satellite GPS.

Reports that iPhones are tracking and storing your every move are causing some Congressional leaders concerned about privacy to question Apple's motives. Reactions to yesterday's revelations that a single unencrypted file on iPhones has been recording location data since the installation of iOS 4 has been mixed.

Some have reacted with amusement, looking at maps of their whereabouts using the open source iPhone Tracker software posted on the web by researchers Alasdair Allan and Pete Warden. Others are wary of Apple's purpose and concerned that this location data is routinely backed up to computers using iTunes.
