Just unpack the phone, keep it in your pocket and walk past them. I had it with me that way last time i came back from LA, and like tishaban, they waved me off. Dont look like you are trying to avoid them, otherwise it's bag-spilling time.

Of course, knowing them personally helps as well, perks of working in the same venue i guess.

You dont have to downgrade to 1.0.2, you can directly unlock it. Wasting two unlock attempts on two firmware versions (1.0.2 and then 1.1.1) will only increases your chances of botching up the unlock attempts and locking it up, especially when you have to do the revirginizing process, which a lot of guys here had trouble with. Google about the NCK Counters in you're interested.

MY pattern of usage:-

Listen to music, every time im out, my headphones are always on my head , surfing via EDGE, especially these two days , for my Sales thread, occasional drop by Starbucks for Wifi for my weblogs, send a couple of SMSes to potential buyers in my Sales thread, answered phone calls to meet up with them, take pics and send it over to my weblog, and also , for yesterday only, looking up places on Google Maps to stop for breaks for my next trip to the US, planned it as a long drive from LA to Sandusky, Ohio. Looking up for places to spend the night, motels or B&B, othewise budget hotels. This is what im looking for in Sandusky, Ohio.

End result? By the time i reached home at near midnight, the 10% battery power left message flashed on. Very good in my books, since im able to do all of that with a single charge.
