Subject: This Sim Card Will Unlock Your iPhone 4, No Jailbreaking Required Message-ID: <BANLkTinBGA0Cp2ZA_CKBOK4J5=GCS22cNw@mail.gmail.com> (From the website - Ed.) "Yesterday we told you about a service that will unlock your iPhone 4 by altering your its IMEI number. "While that sounds good, at $180 it's pretty expensive and there's no guarantee Apple won't be able to reverse it later." This is getting interesting. What finally drove me away from iPhone and to Android was the difficulty of unlocking the phone and using a different SIM.

Our apt building has no such protection. I've lost a few modems from lightning strikes a distance a distance away, as others mentioned. Several of my neighbors were affected too during the same storm. I believe the telco differentiates between aerial drops and underground drops. AFAIK, subscribers served by a line from a pole to their house has protection on it to protect the wiring from the lightning-power currents that could cause a fire. However, AFAIK underground lines would not send out current that would be enough to start a fire or even damage old style Western Electric phones, so protection is not provided. Not every subscriber has a demarc box. Our complex does not have them, and I understand that situation is typical for such older buildings. On the exterior of the building is a large telco junction box, which serves as a mini-distributing frame connecting the underground cable to the lines that serve each apt. Residents do not have access to that junction box. For 99% of the residents not having a demarc is not an issue. They plug a phone into the jack on the wall and that's it. One time I had bad static on the line and I reported it. The telco got back to me that it was fixed "put on a different pair", but the fix was completely transparent to me and at no charge. The same thing happened to a neighbor in a different building. As mentioned, the condo board will not allow the telco to put FIOS in here because the board fears the external boxes will be ugly. I'm not sure that's a valid concern since this thread suggests the FIOS boxes could be installed in the building rear. But then they had trouble getting the cable company to install wires properly and discretely as they promised to do, not run them across sidewalks or thrown over a roof as they did. All underground wiring was a big deal in the 1970s, but it has some drawbacks. Contractors screw up and cut phone lines despite being warned to check first. Winter freeze/thaw cycles can break electric power cables and that's very costly to provide. The original underground transformers had overheating and moisture problems.

Basic electronic equipment - like ADSL modems - invariably have little protection to surges and even small ones can cumulatively degrade performance. >From many years of observing one very popular broadband forum there were always people complaining immediately after storms in every ISP's individual forum. When you took a broader look at the complaints at a regional level you could then see the pattern, and the subsequent dissatisfaction with things until - magically - replacing the ADSL modem seemed to fix all issues. As I said before, good business for the modem manufacturers who sell the replacements and maybe also those who also sell protection devices for the incoming phone line (which aren't common in Australia). -- Regards, David.

How do you think people would react to random messages arriving ~10 times a day to their phones? -- Regards, David. David Clayton Melbourne, Victoria, Australia.

Subject: Re: After Breach, Companies Warn of E-Mail Fraud Message-ID: <firstname.lastname@example.org> Per Sam Spade: >My wife uses her email very carefully to a small group of social >contacts. Yet, she gets some spam. Rule#3: Avoid using a name as your email address. e.g. Pete@Whatver.com = Bad PC@Whatever.com = Better xafgwpq.com = Least spam-prone.... This helps mitigate dictionary attacks where somebody matches a collection of first names to a collection of domain names. "Least spam-prone" and not "Best" bc of anticipated difficulty telling somebody verbally what one's address is. -- PeteCresswell
