Ah, the cost of competition. Samsung’s recently unveiled Galaxy S4 may raise the bar for Apple, but it comes at a price. The new smartphone isn’t expected to launch until April, however we already know how much it cost the South Korean company to build its latest device: $244.

According to IHS Suppli, parts and manufacturing for a 16GB S4 not only cost more than the current Galaxy S3, but also seventeen percent higher than an iPhone 5 with sixteen gigabytes of storage. Seems Samsung is encountering the same financial challenges as Apple when it comes to ensuring your handset remains technologically in step with competitors…

Though Samsung’s new Galaxy S4 smartphone has just a slightly larger display compared to its predecessor, the 4.8-inch Galaxy S3, its five-inch screen puts in the phablet category, especially compared side-by-side next to Apple’s iPhone 5. Because the device won’t launch before end of April, we’re currently unable to compare their form factors in person.

Enter Martin Hajek, a 3D artist who made a name for himself with painstakingly rendered mockups of Apple’s rumored products. The latest from his kitchen: a fresh batch of precise renderings which give us a good idea how the two devices compare size-wise…

Yesterday, iDB reported that T-Mobile’s iPhone 5 is actually a factory tweaked version of the existing AT&T model A1428 device, with support for T-Mobile’s LTE AWS bandwidths. As a result, existing AT&T customers cannot use their iPhone 5 to take full advantage of T-Mobile’s LTE speeds until after the Deutsche Telekom-owned telco launches its iPhone 5 on April 12, at which point Apple will replace the existing A1428 hardware with this re-tooled version.

But a hack has come along claiming to make AT&T’s A1428 iPhone 5 – jailbroken and unlocked (officially or unofficially) – work on T-Mobile’s LTE on the 1700MHz band. It accomplishes this by using a custom carrier firmware that enables support for T-Mobile’s LTE AWS bandwidths. However, it won’t make your AT&T device compatible with T-Mobile’s speedy 3G DC-HSDPA on the 1700MHz band nor will your Verizon iPhone be fooled into accepting T-Mobile’s LTE bands…
