Apple officially takes pre-orders for the iPhone 4 tomorrow, June 15. The device will ship on June 24 with iOS 4 and redesigned hardware. Pricing with a two-year AT&T Wireless service contract comes in at $199 for the 16GB model and $299 for 32GB. It's also possible to purchase the iPhone 4 without a contract but this adds $400 to the price.

Pre-ordering will begin tomorrow in four countries, with 18 additional countries following in July. iPhone 4 can be pre-ordered from Apple Stores, Best Buy and Radio Shack. Pre-ordering will also be available online from Apple and AT&T. In addition to these locations, Wal-Mart will carry the iPhone 4 on launch day, June 24.

Forget about Verizon Wireless. The next US carrier to get the iPhone 4 after the exclusive AT&T deal is over could very well be T-Mobile. Rumors of Apple negotiating with Verizon won't go away, however it seems more logical that T-Mobile could be the next step for iPhone.

Analyst Shaw Wu at the investment firm Kaufman Brothers made waves when he said he expects a T-Mobile iPhone 4 to arrive this fall. T-Mobile has compatible network technology and handles a variety of smartphones on its network. In fact, its parent company already has iPhones on networks in Austria, Croatia, Germany and Holland.

Steve Jobs officially showed off the iPhone 4 today at WWDC 2010. He described the iPhone 4 as the "biggest leap" since the iPhone was first released in 2007. Although photos of the new iPhone have been seen already, the design is quite impressive.

Antennas are integrated into the stainless steel frame of the new iPhone and aluminosilicate glass that's 30 times stronger than plastic makes up the front and back surfaces of the device. The iPhone 4 is 24 percent thinner than the iPhone 3GS.

Ongoing is Apple's WWDC 2010, featuring a bevy of announcements about the new iPad, the new iPhone OS 4 (newly dubbed "iOS4"), Apple's new iAds platform, and the new iPhone itself. Though everyone wants the juicy details about all of Apple's announcements, perhaps the most important tidbit from today's WWDC is when the new iPhone 4 will be available in the US and overseas.

Rumors have resurfaced of ongoing negotiations between Microsoft and Apple involving the addition of Bing to the next generation iPhone. iPhone OS 4.0 could see Bing as an option next to Google and Yahoo if the talks are successful.

Initial reports from TechCrunch claimed that a deal was in place, however now it sounds like this is not the case. In January, Business Week reported that Apple could replace Google with Bing as the default search engine. According to TechCrunch, the purpose of these latest discussions is not to replace Google.
