1) Never ever base purchase decisions on future, unannounced products (in this case, the 3G iPhone). We know it's coming because of common sense and because Apple has hinted at it, but we don't know when or under what circumstances.

2) Don't be an early adopter. The temptation is always there; the financial responsibility is not. The second-generation iPhone will be faster, cheaper, more feature-packed, less bug-ridden. While I find some people's feelings towards Rev A Apple products exaggerated, the general point stands. This is a completely new product of Apple's. Remember the original iPod? No clickwheel (just a mechanical scrollwheel), no Dock connector (therefore, no USB 2 and ver few accessories), no Windows compatibility. By now we have a color screen, contacts, calendars, photos, videos, games, 16 times the capacity and a much lower price. The original iPod was bought by a few hundred thousand people; starting with the 3G, the numbers went up into the millions.

3) Don't overrate 3G. Think a lot about what you're actually going to use 3G for. Web browsing? In that case, keep in mind that 1) the bandwidth matters far less than the latency and 2) the embedded CPU has a lot of impact on the page rendering speed. With later revisions, the CPU will be sped up, but with 3G, latency won't be much better, and bandwidth won't matter as much as you think it will. Where the bandwidth does help is, of course, in file transfers (and thus to a lesser degree also e-mails with large attachments) and – should it ever become practical – an application such as video conferencing.
