I having been exploring Ubin with a GPS for a number of years. The problem with GPS is the babel of formats limiting its usefulness. Fortunately times have changed and formats like Google Earth KML are becoming popular, allowing users to share their maps on-line.
My favorite GPS model is GPSMAP 76CSx. I also bought another similar 60CSx which is more compact and popular. The most important function is tracking accuracy for logging trails under tree cover. Expensive units allow you to download routable maps that provide driving directions. Garmin users are able to download free routable maps for Singapore and Malaysia. Software like Garmin Mapsource or Garmin Basecamp allows you to plan your hike in advance.
There is a profusion of smartphones with similar GPS functions. I pay little attention to such 3G subscription based phones. Overseas telecos are scamming the public with exorbitant phones bills. I was in Dubai when I accessed its 3G for less than a minute before turning off the phone and was slapped with $700 phone bill. Traditional GPS like Garmin uses free satellite signals and all you need is the ubiquitous AA batteries to power them. GPS are power hungry and its important to carry a fresh pack of disposable batteries as backups. There are numerous occasions my GPS becomes a useless dead weight when my rechargeable batteries were not charged fully.

Ordered the Oregon 450 after reading positive reviews. Purchased from Amazon online which includes free shipping. My intention is to get it shipped to Vpost USA address who will then ship to Singapore with attractive shipping rates at one third the shipping costs. Shipping direct would have costs me US$90 instead. The only con is slower transit time but I am prepared to wait.
Turns out to be a mistake. Vpost’s service is absymal. First they refused to accept the shipment while its on its way. They claimed it contains batteries and is therefore considered as dangerous cargo even though Garmin do not ship batteries with their GPS. I have to write a letter twice to them together with description of the packing contents stating it contains no batteries. Next Vpost lost the shipment after USPS delivered it to them. I have to give them USPS tracking number thrice. Took them 2 weeks to tell me they do not have my shipment, giving me a one liner reply asking me to contact USPS myself. A note from them that they checked with USPS with no avail would have helped me claim a refund from Amazon. Disheartened I wrote to Amazon to help me trace my shipment with USPS and within 12 hrs Amazon wrote to me that it considered the shipment as lost and immediately refunded me. No questions asked. Amazon has my customer loyalty. Not for Vpost, .
With the refund, I bought the Garmin Oregon 450 GPS locally which costs me SGD680. The cons for Oregons is the dim screen in daylight and lack of voice prompt. The battery compartment is too tight. Batteries have to be inserted carefully without damaging the contacts which costs $200 to replace. Other than that, it is a vast improvement in UI design. New Garmin models like the Oregons are able to load satellite images by subscribing to Garmin BirdsEye™ Satellite Imagery. The annual subscription costs is US$30. The subscription is worthwhile as I am able to download detailed images for Pulau Ubin. I am now able to confirm position of visible landmarks with better accuracy. Its would have been a chore to take multiple readings 90 minutes apart. I found out earlier that Google Earth images are not accurately positioned and cannot be relied upon.

Update: June 2010.
Progress has caught up. Garmin have a navigation software for Symbian S60v3 smartphones, the Garmin Mobile XT. With pre-loaded maps I do not have to incur expensive data charges. Installed it on my Nokia E72 which have built-in GPS and compass, albeit mickey-mouse in performance. Took as much as 20 minutes to locate satellites. Went to my favorite online site and ordered a Holux bluetooth M-1000 GPS after reading positive reviews. Results looks promising with its tracking accuracy compared well against the popular Garmin 60csx, which unfortunately lacks voice prompt.

Thanks to Google, you can enjoy discoveries made by GPS enthusiasts even if you do not have a unit. With Googlemaps, you can plan your trip to unfamiliar places with directions and location pictures to guide you. Googlemaps is constantly coming out with new features. My favorite is getting directions just by typing zip codes and using its drag and drop feature to plan alternative routes.
Watch this space. I will be adding more tracks and locations of interesting places. You can also download the kml file and view it on Google Earth. With a bit of technical know how, you should also be able to download them into your GPS unit for your next trip to Ubin.
When exploring jungle terrain, make sure you bring a compass with you as it is not easy to get a satellite fix under thick tree cover causing you to walk in circles.
