As the world is now anticipating the next iPhone from Apple (let’s call it as “iPhone 5” for now, shall we?), rumormongers continue to speculate what exactly this smartphone has to offer inside and out. Most of the leaks that we’ve seen in the past couple of weeks focus on the design, some of which are purportedly protection cases or actual parts and assemblies suggesting the iPhone 5 external design. But of course none of these has been confirmed yet, or at least hinted to be real by someone connected to Apple or its vendors.

The latest rumor that surfaces earlier today however, suggests some partner-carriers in Europe may be providing deviously a bit of information which could either amaze or turnoff iPhone users. European operators are purportedly stockpiling Nano-SIM cards in preparation in time for iPhone 5 launch. Though not exactly of any indication such Nano-SIM cards are for iPhone 5 devices — that would leave us skeptical as which handset those SIM cards are designed for?

In any case you haven’t heard about it yet, the Nano-SIM card is today’s smallest SIM card reportedly designed by Apple. It’s the new standardized SIM card format for every GSM, UMTS, and LTE mobile device, approved by the European Telecommunications Standard Institute (ETSI). Obviously the successor to Micro-SIM built on the likes of iPhone 4, iPhone 4S, Nokia Lumia 800, Samsung GALAXY S III, and etc. – the Nano-SIM is 40% smaller than its predecessor, measuring exactly at 12.3mm wide, 8.8mm long, and 0.67mm thick. Its functionality is backward-compatible though with previous SIM card designs, which means you can still cut the usual bigger SIM card with the aid of what could be “nano-SIM card puncher” in any case stocks run out like what happened with the Micro-SIM last year.

In electronics and communications, reducing sizes of parts in a circuitry means more room for other components or better internal design. In most cases, particularly in smartphones, the ultimate result could be a better user experience. But do you really think those who frequently replace SIM cards would be comfortable enough playing with this type of micro-micro-SIM? Maybe, maybe not… For some users, it doesn’t even really matter. Not unless it compromises the entire experience, right? So in any case this rumor turns a reality, how does a Nano-SIM on iPhone 5 sound? [via]
