Smaller SIM Format Standardized
New submitter mk1004 writes "ETSI members have approved a new, smaller SIM format. 'The fourth form factor (4FF) card will be 40% smaller than the current smallest SIM card design, at 12.3mm wide by 8.8mm high, and 0.67mm thick. It can be packaged and distributed in a way that is backwards compatible with existing SIM card designs. The new design will offer the same functionality as all current SIM cards.' Nokia is not happy about the decision, as they believe their version was superior, but they say they're prepared to license the patents essential to the standard."
Nokia would hold the patents.
General Relativity: Space-time tells matter where to go; Matter tells space-time what shape to be.
The new design, being really similar to the old one, also means that Nokia holds the patents for it already.
That is what Nokia is saying they are licensing out, that they were threatening not to allow licensing of before... but they will go along to move the mobile industry forward.

Hope all phones that use these come with a tweezer and magnifying glass! This little sucker is gonna be hard to handle! lol
If given the choice between an ever shrinking SIM card versus the alternative of getting on my hands and knees and begging the CDMA provider to allow my handset on their network, I'll take the SIM card.
Say I find a cool phone from overseas. GSM, I can use it here in the US, although I likely will get stuck with EDGE speeds. Overseas, CDMA providers use R/UIM cards (functionally identical to SIM cards). A CDMA provider here in the US would laugh and tell me where to stuff the phone, since they likely wouldn't allow any device near their network they didn't sell.
It also works the other way around. An unlocked iPhone that has dual radios can go for a world tour and generally find GSM access. A CDMA device that doesn't have a GSM secondary radio would be pretty much a neutered PDA outside CONUS.
Is there any reason the SIM card would have to be physical?
Yes. The SIM is a physical container that protects the computer and data inside it. Note that the SIM is actually a complete computer, not just a hunk of flash memory. When you access the SIM, the security sensitive stuff never actually leaves the SIM card. You don't have any actual access to the security sensitive stuff - the little computer inside the SIM accesses it on your behalf. If it were a software solution (virtual), you would have direct access (via a debugger or similar) to the security sensitive stuff (private keys). Since it is a very physically small hardware solution, you would have to physically disassemble it and hook up microscopic probes to the computer inside, which is very difficult.
