I'm looking to get a secondary battery for my wife's Pearl. It tends to help when she forgets to recharge her battery (often) and needs to get out quickly with a working phone, she can just replace the battery and get going, in the meantime we can let the other battery recharge in an universal recharger.
Anyways, I was checking into some batteries on Ebay, and came across one which comes with an accessory called a "code duplicate clamp". It's apparently there to transfer the code from one battery to another. Why is this needed? I got a Blackberry Bold myself, and I didn't have to do anything nearly so complicated to replace its battery. Is this something for very specific-market Peals only? Here's an ad that I saw this mentioned in:
