Motorola E6 (Motorokr) — Defective Device / Impossible Service

I bought an E6 1 year ago and since then have faced 2 major problems. 3 months ago the LCD went defective and since it was under warranty, i got it fixed. Now the mic has stopped working and when i went to the service station at TTK road, they are telling me its a "Water logging" issue and I have to change the main board that would cost about 85% of the cost of the phone (around rs.8000). My 1 year warranty expired last month and i am not going to spend this ridiculous amount for a MIC. I am still seeking an explanation for the following.

1. Motorola service centers are very few in chennai and they all have work timings not suitable for office goers. Motorola dosent seem to increase the service centers considering the huge defects their products have (Check out the long waiting lines at these centers and youd understand)
2. How can a mic problem be due to "water logging" when all the other functionalities are working well. Come on, give us better answers..I have been a mobile user for a long time and know how to protect my phone from "water" and also It has not rained in chennai for a long time.. and I am sure you can provide with a more 'technical' answer.

I am now seriously considering non-motorola models for me and my family members. Can anyone suggest better models that are "water resistant" since according to motorola, chennai is water logged and not suited for their product line?

Thanks.
