A word to the wise, if you keep your phone in your pocket, do not put all your weight onto it when climbing over a cement wall onto a roof...
Step 1: Parts and Tools
You will need:
A #0 (tiniest) Philips head screwdriver
A prying tool (small flathead screwdriver)
Replacement LCD screen for an LG Rumor.
All I needed was a jeweller's/precision screwdriver set and the replacement LCD. Replacement LCDs can be purchased online at electronics components retailers or on auction site such as eBay. It would probably also reasonable to buy a broken Rumor with an intact LCD second-hand and pirate it for the part. This can be done on classified ads websites such as Kijiji and Craigslist.
