All day trackers - discrepancy

Short answer:
Set yourself as active in MFP, enable positive adjustments, and make sure you keep to your steps.
If you fail to make your steps more than a couple of times a week, set yourself as lightly active and repeat.
Negative adjustments just make it harder to plan your meals if your routine is fairly stable.

I have been maintaining weight for a few months, but now with the switch to iPhone traking it is saying I can eat another 200-300 kcals a day ... this can't be correct, I'll end up putting all the weight back on surely as I am not doing more excercise or changed my weight?

Be very careful: if your routine has been stable increasing calories may well increase your weight. The effects on your body are the only data that are not guesses!

My daily routine is pretty stable, walking to work and back and walking to get lunch - amounts to about 8Km per day on average according to the all day tracker.

sounds around 12,000 steps. you might benefit from setting yourself up as "active" and dealing with a smaller, or no adjustment.

Under the 'old' system, 1750 kcal daily food allowance .. Withings pulse adjustment in my diary, generally negative adjustment of about -150Kcal until around lunch time when had walked 4 Kilometers, then it goes above 0 giving me a positive adjustment of about +100 by the end of the day.
Under the 'new' system, 1750 kcal daily food allowance .. MFP adjustment starts as soon as I begin walking, so this morning I walked to work and am already +50Kcal, and +200Kcal adjustment by the end of the day.

Confused by your numbers here. Are you having an issue because the adjustment doesn't work the same way? You state the same amount of base calories.

So the question is, when MFP asks for the level of activity, I put sedentary, and it seems to have already added in assumed calories for the day - therefore is it double counting when it also gets the real caolries as it is adding them on top.

My basal rate is calculated at 1360kcal - so I would have expected to see any walking I do during the day to be on top of 1360, not on top of 1750 ?

A basic amount of activity is included in the sedentary setting. Your confusion stems from your assumption that you are getting walking calories as an adjustment. You are comparing TDEE's and going with the larger one. It so happens to be larger because you are only including your walking in one of the two TDEEs.

MFP is actually comparing your TDEE as calculated by the activity tracker app to the TDEE estimated by MFP (your original NEAT + any exercise you enter), and giving you an adjustment when the tracker calculated TDEE is larger.

In other words MFP starts: Jim is sedentary he will only burn 1700 Calories today.
Tracker says: Hey I've been tracking Jim all day and he burned 2000 calories.
MFP says: 2000 calories? Wow! Well Jim didn't tell me anything about any exercise he did, and I only thought he was going to spend 1700 calories... better give him an extra 300 credit!
OR
MFP says: 2000 calories? Wow! Jim said he did a 200 calories walk, together with my original guess of 1700 this comes to 1900. Tracker says 2000. Give him an extra 100 Cal credit.
OR possibly
MFP says: 2000 calories? Wow! Jim said he did a 500 zoomba class today, together with my original 1700 guess that comes to 2200. Tracker says 2000. Well the tracker didn't give Jim extra calories, negative adjustments are not enabled, we are staying with the 2200.

As discussed in http://www.myfitnesspal.com/blog/PAV8888/view/negative-adjustments-741838, enabling negative adjustments basically removes MFP from the equation and just ties you 100% to whatever your tracker says you've done at any point of time. This can lead to large ups and downs throughout the day.

And as discussed in the first blog post I refer you to, you should NOT enter some activity in MFP and some in the tracker. Activity should be in either just the tracker, or in both MFP and the tracker. Otherwise some activity will end up never getting counted.

The new tracking system may be more generous in calories it thinks you earned. If your activity hasn't changed and what you've been eating is working for you, then keep eating as you have been. Judge by results. Check your weight every so often.

sounds like something is not counting right. support issue?

Don't seem to have the same issue on fitbit adjustments. Adjustment from sedentary is much greater than from active, for example.

My sister got a huge number of steps because she drove up a mountain and it thought she was climbing steps.

Also, is it synced? For example, with fitbit (which is what I use), you need to set to sedentary and it adds your steps to MFP and adds calories. If you do additional exercise - like I mucked out my chickens for two hours Sunday and did yoga, I logged those exercises - which don't count well as steps - into MFP. You put in the time and MFP tells fitbit to discount all your steps during the time you said you were exercising. Otherwise it would double count.

This is why I stopped using Track My Run. Unless I was very careful with how I set it up, it would put in double steps. The instructions for syncing are good, but you have to read them very carefully and follow their rules.
