Re: Almost a good idea
was it a cheap Chinese SIM? (you can tell by the pattern on the chip)

Another disappointing article.
OK. If you get the network key, you might just about manage to impersonate the SIM (if you also get the IMSI).
Unfortunately, you can't change the SIMs OS - it's in the MASK.
Now Global Platform allows you to modify applets on the SIM, install new ones, etc,
- but the keys are different (SCP02)
- it's only NFC SIM cards - which are nice and new
Finally, Roaming list updates are protected by 03.48 - again different to the network key.
Could the Reg not find someone with a clue to right about these things???
"The SIM is the operators' natural home, but only the most fanatical would expect to run a replacement skin from there. The GSM SIM is best considered an entirely separate computer, connected to the handset over a 9600 baud serial connection, and can no more control the user experience than it can fly a 747, though that didn't stop France Telecom trying the idea with Orange Homescreen back in 2007."
Smartcard Web Server, with the USB connection to the SIM? (sadly only supported by 3.5 handsets)
Which goes to show how laughable FIPs is.
There's very little protection on BB from malicious apps. For instance apps can even inject keypresses. So, one bad app and "all your data are ours". The only reason that BB is used safely, is that they tend to be locked down by the company IT department.

As far as I can tell, the UK is the only country with a functioning digital teletext service - all that "press the red button" malarky is an MHEG 5 application. The most that's been done with MHP in Europe is to run bloody MHP web browsers, with no vidoe interaction.
I remember being bollocked back in the late 90s by some scandi dude unhappy with my company's support of MHEG - looks like we got it right!

“With our system the generator accesses the battery directly, and that really increases the efficiency of the system"
Mobile phone manufacturers spend a vast amount of time on power management and on making sure that the batteries don't blow up. I guess they'll have to test each phone model separately...
