Please read the product description carefully for all unlocked cell phones.

Some unlocked cell phones sold by Newegg may have previously been locked to a specific carrier. A carrier-locked cell phone may often have carrier-specific applications and branding. Some of these applications cannot be unlocked and/or may not function with a different carrier. Also, applications requiring a data plan may result in data usage charges from the original carrier.

In addition, the cell phone box may arrive unsealed and the cell phone may appear previously handled. The unlocking procedure requires unsealing the box and manually handling the cell phone. In this case, the cell phone should not be considered "tampered with" or "defective".

2 out of 5 eggsSimple, but disappointing at times

Pros: Got the phone as an upgrade for $30 from Newegg. Exterior is sturdy and durable. Dropped several times in the last 2 years since upgrade. Easy to assemble/disassemble and access to SIM card and SD card.

Cons: Sluggish often. Ran 2 apps at one time and phone responds very slowly. Sometimes freezes up and I have to pull the battery out in order to reboot/restart my phone. Battery dies within a 8-10 hour period even while I have Wi-Fi, Bluetooth, and GPS off. Dies within a 4 hour period if any of these are activated or running.

Other Thoughts: I was excited about this phone and it's durability. Everyone once in their lives drops or damages their phone so I took advantage of the pricing and obtained this one. When I run Netflix, Pandora, or any other media apps (1 at a time, I didn't run multiple apps) it tends to slow down significantly and sometimes requires a restart. Also, drains the battery. For $30, I'm not completely disappointed since I read reviews that this was made as an obsolete, inferior model which would require you to buy a new phone from Motorola or the upgrade version (Defy+). To anyone contemplating on whether to buy this phone, don't buy it unless you got it cheaper than $30. You'll feel better if it does malfunction later.

5 out of 5 eggsMy first smart phone

Pros: Water resistant. Good battery life if bluetooth, wifi and gps are off. Smooth action. Good sound on both ends. Great little media player too! Overall I'm very pleased with the phone. Mine came with Android 2.2. This phone compares well with my daughter and son in law's phones, one of which is an iCrap.

Cons: There are better batteries available cheap. Google. Not 4G but check coverage. Unless you're sitting at the cell tower you get 3G anyway.

Other Thoughts: With $40/month unlimited text, North America calls and data from SimpleMobile (also available from Newegg) it's a no brainer. For case one word: Otterbox. Already dropped it onto concrete and not a mark.

5 out of 5 eggsSo far impressed...

Pros: Easy to use, good battery with WiFi, Bluetooth running. Built in FM radio receiver so you can listen to "Pravda" on the go (at least in California).

Dropped it a couple of times, robust Gorilla glass. Impressive display clarity.

Great phone for the price. Exceptional Audio quality, even on AT&T Half-Rate GSM network

Cons: Sluggish handling big files, 800MHz OMAP processor

Other Thoughts: Was hoping for Mini-USB charger, but I guess MOT also switched to cr@ppy micro USB connector for charging (as everyone else).

1 out of 5 eggs

Pros: water resistant,
well made high quality phone with low price

Cons: locked bootloader,
no gingerbread upgrade

Other Thoughts: my friend told me today that this phone should come with 2gb microsd but somehow i got 128mb microsd which is for blackberry(shown by the name of the drive when i put it in cardreader) and this is the major reason i write this review and give only 1 egg.
