Question about

This only applies to anyone who uses an AT&T M-Cell with their iPhone 4.

Has anyone noticed with the iPhone 4 and AT&T M-Cell combination the phone calls have been choppy. All of them. I have an AT&T M-Cell in the office where I work and their are multiple iPhone 4's in the office, all with the same problem. Also has happened to another employee at his house where he has his own personal M-Cell.

Any ideas?
Thanks

I have this issue at my home. If I'm in DIRECT line of site, I don't have the problem. Otherwise, I get incoming audio choppiness about every 2 minutes for about 20 minutes of the call. After then, it stops. This also happened on my iPhone 3GS and my family members' iPhone 3G's. I have no solution as of yet. I'm going to try relocating it further away from the wireless routers (about 1.5 yards away right now).

I'm sure you've seen the ridiculous amount of press, but I have to ask. Are you holding it right? Calls degrade in quality so quickly when you hold it near the antenna joint.

Yes. I have two iPhone 4 and have this issue with both of them. Never had it with the 3GS until I "upgraded" to iOS4. I called AT&T and swapped for a new M Cell, same problem with the new one.

Could this be a bandwidth issue? Does the Micro-Cell use your existing internet connection?

I have a new theory about this problem. I decided to sit down, turn my phone wifi off, and get a gps lock in my foyer (next to a turned-off m-cell). I couldn't get a good lock at all. Went next to a window, and I got a good lock. I'm thinking this might be messing with the m-cell's ability to get a reliable idea of tower timing and location (I'm on the edges of 3 cell towers, hence the bad reception in and around my house). I'm going to move this m-cell to said window and see if it improves reception. If it does, but doesn't cover my house as well, then I'll do one of two things:
One, I'll put the router back in the foyer and put an amplified GPS antenna on it.
Two, I'll ask AT&T for a second microcell to it at the opposite corner of my home, near another window, to complete coverage.

I'll keep everyone posted about my success/failure.
