iPhone 5 dual-SIM rumor: Gobi World Phone confusion?

iPhone 5 dual-SIM rumor: Gobi World Phone confusion?

The same source that offered the purported leaked iPhone 5 renders now claims that the fifth-gen Apple smartphone will support "2 SIM cards allowing you to use 2 phone lines." iDealsChina claims the information comes from a reliable tipster, though there's speculation that in fact it's the multi-mode hybrid radio that the site is referring to.

Sprint eyeing T-Mobile USA for potential merger?

Sprint eyeing T-Mobile USA for potential merger?

When it comes to odd bedfellows, GSM and CDMA generally don't mix, but according to the latest carrier rumors that may not be the case forever. Businessweek's sources claim Sprint is in talks with Deutsche Telekon over buying T-Mobile USA in return for "a major stake" in the resulting combined company, with negotiations currently caught up on a fair valuation of T-Mobile.

Verizon HTC Trophy confirmed a World Phone, but won’t launch until June?

Verizon HTC Trophy confirmed a World Phone, but won’t launch until June?

Verizon may well be the last big US carrier to have a Windows Phone device on the market, but going by the latest set of leaked HTC Trophy photos their version may have some advantages over Sprint's HTC Arrive. WPCentral scored some shots confirming what we've suspected since the tail-end of last year, that the Verizon Trophy will be a so-called World phone with both CDMA and GSM connectivity.

No Hybrid Modem for 3G iPad 2; Verizon iPad 2 lacks Global Roaming

No Hybrid Modem for 3G iPad 2; Verizon iPad 2 lacks Global Roaming

Unlike the original iPad, Apple is offering AT&T and Verizon versions of the iPad 2 WiFi + 3G out of the door. Unfortunately, carrier choice doesn't offer quite the flexibility we were hoping for: according to Apple, "the iPad model you purchase is specially configured to work with either AT&T or Verizon — not both."

"While you don’t have to activate 3G service right away, you should choose your iPad with Wi-Fi + 3G according to the carrier you prefer" Apple warns. We'd hoped that the iPad 2 would have a hybrid GSM/CDMA modem which could be used on both AT&T's 3G/UMTS and Verizon's EVDO Rev.A networks, but sadly that's not the case.

iPad 2 supplies to be scarce thanks to super-skinny screen?

iPad 2 supplies to be scarce thanks to super-skinny screen?

Apple's iPad 2 isn't expected to see delays in-between announcement tomorrow and going on sale, but launch numbers could well be limited. According to Goldman Sachs analyst Bill Shope, Apple's choice of a super-thin glass screen for the second-gen tablet has led to supply chain delays, reports AppleInsider; the issue is supposedly not one of technology, but of yield, and Shope believes "volumes [will] ramp fairly quickly as the process improves"

Verizon iPhone 4 teardown: World Phone CDMA/GSM radio inside

Verizon iPhone 4 teardown: World Phone CDMA/GSM radio inside

iFixit has been at it again, whipping out the adjustable spanner set (well, a selection of Torx screwdrivers actually) and taking on Verizon's iPhone 4. We've already given the CDMA smartphone a good going over in our full Verizon iPhone 4 review, but now we get to see the changes inside the iOS handset too. The biggest point of interest is the Qualcomm MDM6600 radio chipset, which actually could've been used to make the Verizon iPhone 4 into a so-called world phone.

Verizon’s iPhone 4: I Was Wrong. Here’s Why.

Verizon’s iPhone 4: I Was Wrong. Here’s Why.

"The surest way for an analyst to generate attention is by making an Apple prediction. Apple has a cult following, and its product development and launch strategy is famously secretive, so the fact that your source is the lunch counter guy across the block from the Hon Hai factory in Taiwan won’t be discovered (or may even be considered authoritative!)"

Those were the opening lines in my first column for SlashGear back in October of 2009. I went on to note that while I don't usually make specific product predictions, I would go out on a limb and provide a guess on when we’d see an iPhone on Verizon Wireless: in 2014, when Verizon Wireless completed its LTE rollout.

Verizon iPhone 4 $50 more off-contract than AT&T version

Verizon iPhone 4 $50 more off-contract than AT&T version

Prior to the Verizon iPhone 4 getting its official launch, at least one analyst speculated that the CDMA smartphone would be more expensive than its AT&T sibling. Unsurprisingly that's turned out not to be the case, at least given how most people will buy the iOS smartphone - with an agreement, it'll be the same $199.99 for the 16GB and $299.99 for the 32GB as the GSM version - however you will have to spend a little more for an off-contract handset.

World iPad with multi-mode GSM/CDMA modem tipped for 2011

Having heard earlier this morning that Apple suppliers are allegedly preparing for mass-production of iPad 2 PCBs in February 2011, now there's speculation on what components might be fixed to them. AllThingsD quotes Wedge Partners analyst Brian Blair, who reckons Apple has picked Qualcomm's multi-mode GSM/CDMA modem for a so-called "World iPad" that could use AT&T and Verizon data networks.
