There are a few areas where I work - namely my [work] office and home office - where we have had to install repeaters (like the Wireless Extender YX510-PCS-CELL) because of poor signal. These repeaters have worked for every Sprint and AT&T phone thus far - except the Pre. In both offices, the repeater has made no difference in the signal quality - which means the phone is unusable - and I wanted to see whether anyone else who has/uses repeaters for signal issues (NOT the Airave - that's a whole different ballgame) is having the same issue.
