If you have a warranty repair (and you have POP, proof of purchase) you dont
have to call Motorola (everyone does anyway) you can just send the phone in.
If you call Motorola all they will tell you to do is the following. First,
remove all accessories
from your phone including your cases, batteries (they have lots) cig cords
etc. Jot down your phones ESN or IMEI number and then wrap securely. Use
common sense, wrapping phone up in toliet paper or 3 wraps of newspaper is
not "securely".And remember, the finished package should not be able to be
shaken and the phones sliding all over the place. Bad sign!! Place your
phone in a suitable shipping container along with a letter stating the most
detailed explanation of the problem . You cannot give them too much
information. If the problem only aoccurs when your chewing Wrigleys Gum,
tell them. Then you need to include the return shipping info and contact
numbers.Make sure the ESN/IMEI number is also on this letter. Make sure you
include a COPY of the POP (Proof of purchase) with the letter as well. Make
sure they can find you while your sleeping. If they cant find you, you wont
be the first person to get your phone back after two weeks, unrepaired, with
a letter saying, " Dear Valued Customer, we tried to get a hold of you and
couldnt. So here is your phone unrepaired. It has a bad gizmoo and is not a
warranty issue. If you would like, send us the phone and $100 and we will
replace it.Thanks for buying Motorla!" Get my point!!? Then, and this is
important. Put the SERIAL/IMEI number EVERYWHERE and most important, THE
OUTSIDE OF THE SHIPPING BOX, that is imperative. Motorola receives your
phone at the repair depot by your ESN/IMEI number and Shipping TRACKING
Number. Only use a Shipper that will give a tracking number. When you call
Motorola to discuss your phone, the first question the automated attendant
wants is your phones Mobile Phone Number. From there it will go to the IMEI
for GSM phones (It does not ask for ESN on auto attendant) and then the
Shippers Tracking Number last..Always make sure the phones IMEI or ESN is
marked CLEARLY on the outside of the box as well as your complaint letter
inside the box. I cannot stress that enough. Finally send to  (This reflects
some different verbage then my original posting, the actual numbers of the
address are all the same):

Time. If you follow the above procedure, I can assure that, at least the
delivery and correspondence facet of your repair will go smoothly

That depends on you?  When I was younger (and had good eyesight and
steady hands) I worked on pretty small circuitry.  If you;ve never
repaired micro-electronics before, though, I wouldn't suggest it.

Motorola or, possibly, your carrier's repair shop, if they do repairs.
